Build me an Android App

Hello, We are a Recruitment & Staffing Agency based at Chhattisgarh. 1. I want to develop a simple interface where candidates can view and apply to the current jobs. 2. Home screen will contain a. Images/graphics sliding on top 30% screen b. Current Jobs scrolling on the next 50% screen with apply button on each c. "New Registration" and "Existing Registration" button in the bottom 3. New registration will open a form along with payment gateway and attach resume option and will generate a Unique registration ID attached to the contact number(If possible OTP verification in each login) 4. Existing Registration will ask for Registration number(if possible OTP verification) and take to current jobs and apply now section. 5. Excel record generation in the back-end, candidate search with the help of keywords, mobile number and registration id. 6. Payment Gateway Rest will be improvised on the first template. Thankyou
